    Sammanfattning : The gastric pathogen Helicobacter pylori is a Gram negative bacterium which may cause diseases such as peptic ulceration and gastric adenocarcinoma. It colonises a host by attaching to the gastric epithelial cells, an attachment mediated by outer membrane proteins on the bacterial surface, e.g, the blood group antigen binding adhesin, BabA.

  4. 9. Photon Upconversion through Triplet-Triplet Annihilation: Towards Higher Efficiency and Solid State Applications

    Författare :Damir Dzebo; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; solar energy conversion; triplet-triplet annihilation; energy transfer; fluorescence anisotropy; anti-stokes; photon upconversion; excited state; porphyrins; photochemistry; photophysics; delayed fluorescence; dendrimers; anthracene; oligomers; spectroscopy;

    Sammanfattning : The sun is the only renewable energy source that can accommodate humanity’s energyneeds today and in the foreseeable future. The sunlight reaching the planet’s surfaceis filtrated through the atmosphere, reducing its UV-light intensity in the 300-400 nmrange, which indeed can be harmful to life as we know it in too large doses.

  5. 10. Formation of Mesoporous Materials and their use as Lipid Bilayer Supports

    Författare :Maria Wallin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; tethered lipid bilayers; meso-ordered PEG-DA hydrogels; dendrimers; porous silica and titania; lipid bilayers; biosensing;

    Sammanfattning : Mesoporous materials have acquired great scientific interest in various applications; something that is largely due to that their properties, such as pore size, pore orientation, material composition and surface chemistry, can be controlled to a large extent. One idea, which has been investigated in this thesis, is to use mesoporous materials as supports for lipid bilayers and by doing so fabricate devices that mimic the cell wall and at the same time has sufficient mechanical robustness for practical use.
